TOKYO (AP) - Japan's Health Ministry says tests have detected radiation in more types of produce, and in more places.
In addition to spinach, the tests found excess amounts of radioactive elements on canola and chrysanthemum greens, and some of it turned up in areas where contamination hadn't previously been recorded.
The government has halted shipments of milk from the area near a leaking nuclear plant after finding tainted milk at four farms.
Tokyo Electric Power Company says two of the six reactor units at a damaged nuclear plant are now safely under control. But efforts continue to control four other reactor units that began overheating when the earthquake-triggered tsunami disrupted the plant's cooling systems.
Meanwhile, Japan's police agency says more than 8,400 people are now confirmed dead in the disaster and nearly 13,000 are listed as missing.
